Gerry (Aaron Schwartz) is not looking forward to his summer vacation, since he'll be spending it at a camp for overweight boys in order to shed pounds. Fortunately, a kindly couple, the Bushkins (Jerry Stiller, Anne Meara), run the camp and make the process fun and relaxed. However, they're soon forced to declare bankruptcy and sell the camp to Tony Perkis (Ben Stiller), a fitness fanatic who turns the camp into a living nightmare of over-the-top training. But the kids plan to fight back.
